My first antique blade, help with ID?

[midelburgo]

I think you have two inscriptions from two different times/places.

The one with Me fecit Solingen has "E"s that you often find in XVIIth German exports into Spain, imitating a sort of Spanish XVIth c. script. You find many swords attributed to SEBASTIAN HERNANDEZ, with that sort of "E"s.

On the other hand, NEC TEMERE NEC TIMIDI is not a motto that you find in Spanish swords. Its "E"s are more an Italian (standard) type.

Maybe your knife (and possibly some Scottish backswords) could have started life as a double edge blade.

I put Sebastian Hernandez and sword in google, and I got this officers 1728...
